Ac fans feature smart thermal controls

A 6-in. energy-efficient ac-fan with smart
thermal controls is an addition to the OA172 series of axial fans.
It features a ball-bearing design that delivers airflows of 105 to
200 cfm with reduced noise levels of 37.5 to 50.8 dB.

The fans provide thermal control to reduce power
consumption by increasing or decreasing fan speed according to the
ambient air temperature. They provide up to 30% energy savings
versus similar sized single-speed fans. They measure 172 x 51-mm,
feature an impedance- and thermally-protected motor, and an
aluminum alloy frame with a UL94V-0 plastic impeller. The rated
speeds range from 1,600 to 2,600 rpm, and feature an operating
temperature range from –10° to +70°C.
